Most of the hydroelectrical projects, especially those with high output power utilizing large size turbines in their powerhouses, the powerhouse is usually founded on sound bedrock. This will eliminate long term foundation settlement, potential instabillity due to earthquake, liquefactions, etc. The turbines created vibration during operation, which may result in movement or settlement if founded on soil.
However, for small hydro projects (such as those who generating up to 10MW power), bedrock foundation may be uneconomical, if it is not found close to the existing ground surface.
My question is whether there are documentation about small hydro cases, in which their powerhouse is founded on soil or overburden. Is there technical papers, conference papers that discuss about this specific issue?
Thanks for info.
